DYEING APPARATUS.

SPECIFICATION forming part of Letters PatentNo. 428,614, dated May 27,1890.

Application filed September 1'7, 1888. Serial No. 285,588. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES L. KLAUnER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inDyeing Apparatus, of which the following is a specification.

My invention relates to dyeing apparatus; and it consists of certainimprovements which are fully set forth in the following specificationand shown in the accompanying drawings, which form a part thereof.

In the dyeing of yarn or other materials it is often necessary in orderto obtain a particular tint or shade of color to subject the material toa series of baths of different dyeliquor, or in ordinary cases to a bathof mordanting material and then to one or more coloring-baths. At thepresent time this is performed with a great degree of inconvenience andtrouble by the necessity of removing the material from the vatcontaining one liquor and immersing it in the others successively,according to the number of baths to which it must be subjected.Manifestly this consumes alarge amount of time and labor, and requiresIn apparatus embodying my improvement it would be convenient to make thedye or mordant bath in the dye-vat and then pump the liquor out into thereservoir-tanks. It also happens that after a short while the dye orother liquor loses a large portion of its strength and requires to beenriched by the admixture of a new quantity of dye-matter.

It is the object of my invention to accomplish the successive subjectionof the material to a series of baths of different liquor, and whendesired to make or to enrich the liquor in the tank by mixing with it anew quantity of dye or other stuff used without removing the materialfrom the vat. For this purpose the dye-vat is connected by pipes to anyrequired number of tanks'or reservoirs, according to the number ofdifferent baths to which the material is to be subjected. Through thesepipes the liquor may flow from the tanks into the vat, the fiow beingcontrolled by valves. The vat is connected by a pipe to a pump which isdischarged into either of the reservoirs or tanks, whereby the liquormay be drawn off from the vat and placed into one of the tanks, andanother bath of liquor allowed to flow into the vat from another tank.For the purpose of enriching the bath, instead of thus drawing off theliquor, additional dyestuff may be forced or allowed to flow into thevat in the manner hereinafter described.

To accomplish the making or enriching of the dye-bath, I provide a pipeentering the bottom of the vat and furnished with apertures. At theupper end of the pipe in a bowl or receiver the dye is placed and mayrun into the vat by gravity or be forced therein by a jet of air, gas,or other suitable medium. Simultaneously with the admixture of the dyesteam may be blown into the liquor in the vat by additional perforatedsteampipes.

There are many details to my invention set out later on.

In the drawings, Figure 1 is a plan view of my improved dyeingapparatus. Fig. 2 is a side elevation of the same, and Figs. 3 and 4 areviews of modifications of mechanism for introducing dye or other stuffto enrich the bath.

A is a dyeing-machine,with the particular form or construction of whichthis invention has nothing to do, as the invention is equally adaptableto any of the known machines or vats. I prefer, however, to employ thedyeing-machine set out in my Letters Patent No. 377,393, dated February7, 1888, which is the one shown in the drawings.

B are tanks to contain the different mixtures of liquor to which thematerial is to be subjected. There may be any number of them, asdesired, and their capacity should 1 be at least that of the dye-vat ofthe machine A. These tanks may be either open or closed at the top.

0 are pipes leading from the tanks B to the dye-vat. tanks B stationedat a slight altitude above the vat and the pipe 0 leading from thebottom of the tanks to the bottom of the vat, so that the liquor mayflow into the vat by gravity. Each tank may have a separate pipeconnecting with the vat, or these pipes may be united in one enteringit.

D are plugs or valves by which the flow of liquor from the tanks 13 maybe opened or closed. I do not limit myself to the'particu- In practice Iprefer to have the lar form of valve-plugs shown, for while I preferthat construction it is evident that any other satisfactory form ofvalve may be employed.

E is a pump connected on the vacuum or suction side with the dye-vat bya pipe F and on the discharge side with the tanks 13 by a pipe G andpivoted nozzle ll,which may be brought in position to conduct the liquorto any of the tanks B, as indicated in dotted lines Fig. 1.

I is a steam-pipe provided with a valve 71, entering the bottom of thedye-vat and having a number of holes or perforations for the escape ofthe steam into the liquor to raise the temperature of the bath to thedesired degree of heat. I prefer to have this pipe extend about thebottom of the vat in the manner shown in dotted lines in Fig. 1.

J is a small receiver for the dye-stuff which may be used to enrich thebath,opening by a pipe K, having a valve in, into the dye-vat. I preferto have this pipe K extend some distance into the dye-vat and to provideit with holes or perforations (see Fig. 1) to more thoroughlydisseminate the dye-stuff through the liquor. The pipe K ispreferablyarranged parallel to the steam-pipes I and transversely acrossthe vat.

L is a blower connecting with the pipe K below the valve It, by whichair or gas maybe blown into the pipe K to force the dye-stuff from thereceiver J. The pipe M, connecting this blower L with the pipe K, isprovided with a valve m, by which its operation may be con trolled. InFig. 3 is shown. a modification in which these valves 7.: and m areconnected by a link N, so that upon opening the valve 112. the valve 7.1is instantly closed, and vice versa, and the dye-stuff in the pipe K isforced into the dye-vat. It is practically necessary that this valve 7i:should be closed when the valve in is opened, or else the dye-stuff andsteam would be forced out of the receiver J.

In Fig. 4 is shown a modification in which a pressure-pipe O is providedwith a valve 0, and a nozzle 1 is inserted into the receiver at theopening of the pipe K, through which air, gas, or steam may be used toforce the dycstuff into the dye-vat through the pipe K.

It is evident that instead of enriching the dye-liquor from the receiver.I it might be drawn oil? into one of the tanks 1; and there enrichedbythe addition of the dye-stuit'; but I prefer to use the receiver .lfor this purpose, because it is equally effective and causes less delay.

From this description the operation of my apparatus will be readilyunderstood. The material is placed in the dyeing-machine A, the vat ofwhich is filled from one of the tanks B with the desired liquor or maybe filled directly. \Yhen itis desired to change the bath, the pivotednozzle is placed in connection with an empty tank 1; and the pump E isput into operation. \Vhen the liquor is thus entirely withdrawn from thevat and discharged into one of the tanks B, the valve D of that tankwhich contains the liquor next to be used is opened and the liquor isallowed to flow into the vat, subjecting the material to a new bath, andso on, as required. It is apparent that the supply-pipes U of the tanksmightbe connected to the dye-vat through the pump E, which might then beused both to pump the liquor from the vat t0 the tanks and again fromthe tanks to the Vat; but I do not considcr such a process expedient ornecessary unless for some reason it is inconvenient to connect the tanks13 directly with the vat and allow the liquor to flow therefrom bygravity, as described. In the receiver .l' the enriching dye-stuff isplaced and the valve 701's opened. The dye-stuff then flows down throughthe pipe K, and upon closing the valve In and opening the valve on itmay be blown or forced into the bath through the perforations in thepipe K within the dye-vat.

The steam for the bath is admitted by pipe I, and simultaneouslytherewith or separately the dye-stuff may be admitted by the pipe K withair, gas, or other medium. A dotted pipe S is shown as connecting thestean1-pi pc I and the dye-pipe K, (see Fig. 2, so that steam may beused, if desired, in place of air.

By having separate pipes for admitting the steam for heating the bathand dye-stuff for coloring it the steam. may be regulated to any degreeor be made to act continuously with out interfering with the desiredadmittance of the dye-stuff. Thus the dye-stuff may be admitted veryslowly while the steam for heating the bath may be allowed to rush inunder full head, and thus keep up the boiling temperature with a gradualsupplyof the enriching material.

The invention is equally applicable to scouring purposes.

The minor details of construction which are here shown are not to beconsidered limitations of my invention, for while I prefer them inpractice it is apparent that they may be varied in many ways withoutdeparting from the principles of my invention.

llaving now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with a dye-vat, of a reservoir to contain enrichingstull, a pipe leading from said reservoir and entering the vat below thelevel of the liquor therein, a valve in said pipe, and a valvedblast-pipe (through which no dye-stuff passes) entering saidenriching-pipe to blow enriching stuil from said reservoir through theenrichingpipe directly into the dye-vat below the liquor-level, and asteam-supply pipe independent of the enriching-pipe to supply steam tothe d ye-vat for boiling purposes.

2. The combination, with a dye-vat, of a reservoir to contain enrichingstnif, a pipe leading from said reservoir and entering the the level ofthe liquor therein, an pipe opening into said enrichingvat belowair-blast ITO I11 testimony of which invention I hereunto set my hand.
